I'll confirm everything Godfrey wrote and add one more detail: ordinary lens glass filters out virtually all UV. I have a friend who occasionally shoots UV and he has to use a special fluorite glass lens to do so (it's an ungodly-expensive Nikon macro specifically made for UV photography). Flare from filters, especially non-multicoated filters, can be a real issue. Particularly veiling flare which isn't always obvious. -- Mark Roberts - Photography & Multimedia www.robertstech.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
